Definitions

  • the invention relates to a side pressure piece for the elastic lateral clamping of a workpiece against one or more stops available on a base consisting of a housing which can be attached to the documents and a holding pin fastened in the housing and partially projecting out of the housing for the purpose of bearing against the workpiece, which in two lateral Directions against elastic means is movable.
  • Such side pressure pieces are known for example from the older German patent 2 503 246.
  • the retaining pin is embedded in an elastic material and thus held in a springy manner, i.e. that is, if he is brought out of his normal position by applying a correspondingly large force, then he tries to return to this normal position.
  • a side pressure piece for the elastic lateral clamping of a workpiece against one or more stops on a base consisting of a housing which can be attached to the base and a retaining pin which is fastened in the housing and partially protrudes from the housing for the purpose of bearing against the workpiece two lateral directions is movable against elastic means, which is characterized in that the retaining pin is provided with a collar abutting the housing wall and is pressed by a compression spring arranged in the housing between the housing base and collar with its collar against the inwardly angled housing edge.
  • the retaining pin can be deflected from its normal position in any direction, and with it the collar is moved out of its normal position against the spring force. That means that the spring force tries to push the collar back into its normal position and at the same time to bring the retaining pin back into its normal position.
  • This restoring force is generated by the compression spring, which is arranged between the housing base and the collar.
  • the stronger the spring force of this compression spring the greater the restoring force with which the retaining pin ultimately wants to return to its normal position.
  • the side pressure piece according to the invention is distinguished by a much greater insensitivity to material fatigue due to the use of a conventional compression spring, so it can be subjected to virtually unlimited static and dynamic loads. Furthermore, the compression spring allows greater spring travel than the elastomeric materials used in the known side pressure pieces, it is thus possible to compensate for much greater tolerances in the workpieces to be fastened with the side pressure piece according to the invention.
  • the side pressure pieces according to the invention are characterized by greater resistance to the action of heat and chemicals, in particular all types of solvents, and they are almost insensitive to corrosion even when using stainless spring steel for the compression spring.
  • the collar of the holding pin is provided with a partially spherical outer surface in the side pressure piece according to the invention.
  • a partially spherical outer surface allows the retaining pin to be deflected and, at the same time, the collar resting against the housing wall to tilt without the collar losing its guidance on the housing wall.
  • Such an embodiment is characterized in particular by a very uniform change in the spring force when the holding pin is deflected from its normal position.
  • the housing is partially hollow in the region of the collar.
  • Such an embodiment provides good guidance over the entire deflection range even with a simple disc-shaped collar; on the other hand, such an embodiment in connection with a part-spherical outer surface of the collar is almost optimal for guiding when deflecting the retaining pin.
  • the restoring force of the retaining pin can, as already mentioned, be varied in that a spring of different strength is inserted into the side pressure piece according to the invention.
  • the side pressure piece according to the invention can thus be supplied with different restoring forces.
  • the spring force of the compression spring is designed to be variable by means of an actuator.
  • Such a change in the spring force of the compression spring can thus be brought about by means of an adjusting screw which is arranged in the housing base and provided with a stop for the compression spring and which is optionally locked with a lock nut or in another known manner.
  • the spring force of the compression spring in the housing can be varied within a wide range and thus also the restoring force of the retaining pin.
  • the holding pin can have any shape, but it has proven to be useful if it is designed as a cylindrical pin and is provided with a rounded tip protruding from the housing.
  • the retaining pin is provided with a spherical head protruding from the housing.
  • Another version provides a holding pin with a conical head protruding from the base. All of these embodiments are suitable for clamping workpieces between one or two fixed stops and the retaining pin.
  • the housing of the side pressure piece according to the invention which is expediently made of metal, is expediently embedded flush in the base, so that only the retaining pin protrudes from the opening of the base.
  • the retaining pin is provided with an extension beyond the collar, which represents a centering for the compression spring, which is usually of spiral design.
  • a corresponding projection can also be attached to the bottom of the housing, which also serves to center the compression spring and thus fulfills the same purpose discussed above.
  • the side pressure pieces according to the invention are also distinguished from the previously known side pressure pieces in that they can absorb or transmit pressure forces not only in two directions, but in three different directions.
  • the spring materials used for the construction are commercially available in a wide variety of specifications, so that the pressure pieces according to the invention can be produced with standard materials for all conceivable requirements.
  • the side pressure piece according to the invention shown in Fig. 1 consists of a holding pin 1 partially enclosed in a housing and thus insertable into the opening of a base, which is provided with a collar 3 resting on the housing wall and one arranged in the housing between the housing base 4 and collar 3 Compression spring 5 with its collar 3 is pressed against the inwardly angled edge 6 of the housing 2.
  • the collar 3 of the retaining pin 1 is provided with a partially spherical outer surface with which it rests on the housing wall. In the case of the cylindrical housing wall, this part-spherical outer surface allows the holding pin to be deflected and the collar to tilt at the same time without the collar losing its guidance on the housing wall. Through this part-spherical outer surface of the federal government, a very uniform transmission of the spring force to the deflection of the retaining pin from its normal position is achieved.
  • an inward bulge 7 is arranged, which serves to center the compression spring 5.
  • An extension 14 of the retaining pin 1 has the same purpose beyond the collar 3. This extension is also enclosed by the compression spring and thus serves to hold the compression spring in its position.
  • an adjusting screw 8 is adjustably arranged in a corresponding threaded opening in the housing base 4.
  • This set screw 8 has a support 9 for the compression spring 5. This support can be moved closer to the collar 3 of the retaining pin 1 by turning the set screw, whereby the tension force of the compression spring 5 is increased.
  • the set screw 8 is locked in its desired position by means of a lock nut 10.
  • FIG. 3 shows the side pressure piece according to the invention in section, used in a base 11.
  • the workpiece 12 is clamped between a stop 13 and the retaining pin 1 of the side pressure piece according to the invention and is held in this position by the restoring force of the retaining pin 1.
  • the holding pin can thus be moved laterally in all directions and it can also move in the vertical direction against the force of the compression spring 5.
